Gas Welding Equipment
There can be no doubt that MIG (Metal Inert Gas) welding is a great leap forward in the advancements of welding technology. The almost perfected, all-in-one process makes MIG welding lot more convenient. Load the filler wire onto the machine, set your amperage, and there you go.
Learning the basics of the MIG welding equipment may call for some initial strain. But once you become familiar, MIG welding is an easy process and you will be able to obtain clean and tidy welds. In MIG, a spool of solid-steel wire is fed from the machine, through a liner, then out of a contact tip in the MIG gun. The contact tip is either hot or electrically charged, when the trigger is pulled and melts the wire for the weld puddle.
There is no denying that MIG welding is costly when compared with the other processes. Machines as also the filler wire are much more expensive than stick welding machines and electrodes. Besides, MIG welding applications are also restricted, as it may not be suitable for all types of welding.
There are automatic and semiautomatic MIG welding machines. An example of automatic MIG is a robotic arm often seen welding car frames in an auto assembly plant. Semiautomatic MIG welder is when an operator holds the MIG gun and manipulates the weld pool. In automatic MIG, an operator sets up and watches over the machine. An experienced welder is the preferred because he has the right touch and knows what it means to be in the welding zone.
